Human glutamate carboxypeptidase II (GCPII) occurs in the central nervous, system as well as in human prostate (where it is called prostate-specific, membrane antigen; PSMA). Inhibitors of the enzyme have been shown to, provide neuroprotection, but may also be useful for the detection, imaging, and treatment of prostate cancer. Crystal structures were determined of, the extracellular part of GCPII (amino-acid residues 44-750) in complex, with two potent inhibitors, quisqualate and 2-PMPA (the strongest GCPII, inhibitor to date), at resolutions of 3.0 and 2.2 A, respectively. In, addition, models were constructed for binding of the inhibitors, willardiine, homoibotenate, L-2-amino-4-phosphonobutanoic acid and, L-serine-O-sulfate to the S1' site of the enzyme. The common denominator, for high-affinity binding to the S1' site is the formation of two strong, salt bridges.

== Function ==
 +
[https://www.uniprot.org/uniprot/FOLH1_HUMAN FOLH1_HUMAN] Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would appear to be physiologically irrelevant. Involved in prostate tumor progression. Also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC.
